Former CIA official David J. Rush has reached a tentative plea agreement after being charged with theft of public money for allegedly inflating his salary. A federal judge on Friday extended the deadline to formally indict him until Oct. 8, allowing prosecutors and his attorney to finalize the agreement and potentially avoid a public trial that could involve substantial disputes over classified material. Court records say Rush falsely claimed military leave and degrees from Clemson University and Rensselaer Polytechnic Institute. An FBI search of his home also found about 300 gold bars worth more than $40 million, roughly $2 million in cash and about 35 luxury watches, although his attorney says the criminal charge is unrelated to the gold.
